' To all whom it may concern:

Be it known that I, FRANK'L. HARMON, a citizen of the United States, and r'esident of Beverly, county of Essex,,Commonwealth of Massachusetts, have invented an Improvement .in Shoe-Button Staples, of

which the following description, in connection with the accompanying drawings, is al specification, like characters 0. the drawings representing like parts in each of the several views. 7 v

This invention relates to staples and par ticularly' to staples for. special uses. For purposes of illustration the invention is shown as embodied in a button attaching staple a particular object of the inventionings, in which,

Figure 1 is a perspective view of one'of the staples which constitute the subjectmatter of this invention;

Fig. 2 is a plan view, illustrating the manner in which the securing of the shoe button to the upper by means of the staple is effected; I

Fig. 3 is a sectional view showing portions of the staple applying mechanism and the manner in which the staple is inserted and' clenched, and

Fig. 4 is a perspective view of stock to which buttons-have been attachedby means of the staples, this view illustrating particularly. the adjustability of the buttons when thus secured.

Ordinary button fastening staples comprise a pair of legsand a head having a curved button eye receiving notch or recess and two inclined connecting portions ex tending from? this notched or recessed por-' tion to the legs. These sta les'are usually formed of round wire an groove is just large enough to receive the button eye. A driver embracing the notched or recessed ortionof the staple and engagingthe s oulders or connecting portions just described is used to drive the staple this strain) lengthwise. of the staple tends f to turn 'the staple over'in the stock owing the insecure'fasteningwhi 'h ispossible with 7 5 a piece of the notch or when a button is to be. attached and the- Patented Apr, 16,: 191s.

staple 'isso driven and clenched that its ends curl back 31p into, the stocks With this type of .staple it is essential that the buttons be attached with great care and inlocations exactly corresponding to the locations of the buttonholes in the other side of the upper, a condition which it has been.

'found impossible to more thanapproximate in practice. 7 The resultisthatthere is more or less strainupon thebuttonsjlengthwise of the staple and thusthey tend to wedge under the rounded shoulder between the notch and the-inclined connecting portions of the head '-'whereby' *they tend to; work the staple loose in? the stock and thus' to causethe button to become detached. -1Frequently a staple ofthe construction described.

An important object of this invention is to provide a staple which will allow the button to adaptitself to inaccuracies in its setting and which, moreover, will so" securelyattach the button'that the button cannot work the staple loose, even if the provision for adjustment is not s'ufficient to prevent longitudinal strain upon the staple.

To this end the illustrated staple is pref erably made from'material of such a crosssection that .its, inside face is perfectly flat and will lie flat against both sides of the stock,--the staple being so shaped that the button receiving recessis of such an extent as to provide for a movement of the'button eye lengthwise thereof upon the bar 1 to permit the button to adapt itself to inaccuracies either in the setting of the staple or in the location of the buttonholes, this recess being herein shown as formed by bending the material so that there are. two substantially right angles 2 between the top 1 and sides 3 of the recess, and'two more substan-' tially right angles 4 between the sides 3 of the recess and the portions 5 which connect the recess with the vertical legs 7 of the staple. The connecting portions 5., being parallel to the bar'l, W11]. thus'lie flat upon.

the upper surface of the stock, as shown at the right portion of Fig. 3, when the staits ple is clenched and-there will be no oppor- I tunity for the button eye to wedge itself under'either of the shoulders 4 between the horizontal portions and the sides of the recess. The connecting portions 5, or at least one of them, are preferably of such length that a staple leg and its adjacent portion 5 may be driven through the eye of the button in the button stapling operation, as shown at'the right, in Fig. 3.

i To provide for eii'ectivegripp'ing of the inner or under face of the stock when the legs are clenched, the points upon the staples are formed by simp y beveling the outer faces of the legs down to or approximately to the inner surfaces, as shown at 1A in Fig. 1. Thus the flat-inner faces of the staple legs are effective in securing a firm grip upon the stock wleep the staple is clenched, as shown in Fig. 3. Moreover this permits the use of,., a clenching cavity which 'is comparatively shallow, since the bevels tend to turn the staple legs toward each other and therefore the staple when clenched will not project appreciably, if at all, above the inner or under surface of the stock, thus contributing to the comfort of the wearer of the shoe.

In connection with the use of the expression right angle in the specification and claims, it will be understood that allowance is made for such rounding of the corners as is necessary for or incidental to proper bendin of the material from" which the staple s formed, the ezgpression being intended to define general directions and effects and. substantial characteristics.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. A staple formed of wire flat u on the inner faces of said staple, said stap e comprising a head having a substantially rectangular elongated recess, a'pair of legs and connecting portions between. the recessed portion of said head and saidlegs extending outwardly from the recess at substantially right angles to said legs.

.2. As a new article of manufacture, a but ton attaching staple comprising a pair of legs, a head having an elon ated recess there in formed by a substantially straight button, retaining bar uponwhich the button may adjust. itself and two endb'ars arranged at right angles to thefirst mentioned bar,

. said staple having stock engaging portions 1 connecting said recessed portion with said l egs. I

3. A staple having two legs of substantially equal length,'a head provided with a 'substantially' rectangular. elongated recess Leearea and comprising portions extending from said recessed portion tosaid legs at-substantia-lly right angles to said legs, said staple being formed of-wire flat upon the inner faces ofsaid staple and beveled at the entering ends of said legs from its outer surface substantially to its inner flat face.

4. A button attaching staple comprising a pair of legs, a head having formed therein an elongated button eye receiving recess with sides substantially parallel to said legs and having stock engaging portions connecting said sides with said legs, both of said stock engaging I portions extending outwardly from the recess and atsubstantially right angles'to said legs and one of them be- I ing of such length that it together with the adjacent leg may be inserted through the button eye in the button stapling operation.

5. A button attaching staple comprising stantially straight elongated button retaining bar upon which the button may adjust itself, and stock engaging portions lying flat upon the stock, extending outwardly from the head insubstantial rectangularitv with the end' portions thereof. whereby the wedgingfof a button eye under a stock engaging portion is avoided, anda legat the outer I end ofreach stock engaging portion.

. 7. A button attaching staple having a pair of legs and a head comprising a substantially straight elongated button retaining bar upon which the button may adjust itself,

and stock engaging portions lying flat upon the stock, extendlng outwardly from the head and joining the head to the legs.

In testimony whereof, I have signed. my

name to this specification, in the presenceoftwo subscribing witnesses. I
